What is one of the ultimate expressions of love? Sacrifice. We might think of the direst of examples, like laying down your life for someone else. But maybe it’s the mom who loves and cherishes her kids so much that she makes sure they are fed, even if she is hungry. Or the teacher who sacrifices time to help a struggling student. Olaf, the snowman from the 2013 Disney movie Frozen, said it best: “Love is putting someone else’s needs before yours.”
